FPGA Based Modified Space Vector PWM technique for induction motor drive

This paper presents, In SVPWM based VSI fed induction motor drive, is compared to conventional PWM method. And proposed method hardware implementation of using FPGA kit in SPARTAN-6. In this work, the authors proposed the idea of THD reduced the output of VSI fed induction motor drive. Then improved dc link voltage and case studies of open loop and different control technique used to control VSI fed induction motor are presented. Conventional method used to PWM technique control method and proposed method space vector modulation technique used. Prototype hardware is implemented to FPGA controller used to results are presented. The drive system has advantages like reduced THD and improved motor speed.
